| Research Abstract |
We performed fMRI in patients with pure motor stroke using two somatosensory stimuli (palm brushing and proprioceptive input). Both the stimuli tonon-paretic hand activated contralateral primary sensorimotor cortex, supplementary motor areas and ipsilateral cerebellum. Stimuli to the paretic hand also activated brain motor network, although to a lesser extent. The findings suggest that physiotherapy that employs somatosensory input via the paretic hand may be used as a first step to activate rehabilitation-dependent changes in the motor network in the brain toward restoration of motor function.
